This invention relates to an anuscope adapt ed to be used by physiciansand surgeons in the examination, diagnosis and treatment of the terminalportions of the alimentary canal and involves the use of a tubularmember open at both ends and having its distal end provided with alaterally curved and tapered entrant section swivelcd thereto at oneside of the opening to automatically direct the entrance oi the tubularmember into the more or less sinuous duct without irritation thereoi",the proximal end of the tube being arranged to receive a suitable lampcase carrying a relatively small but powerful incandescent electric lampprojecting into the interior oi? the tube for illuminating; theanatomical parts under examination or, when desired, the lamp case maybe removed. and replaced by an irrigating device inserted into theinterior of the tube through the proximal end thereof :tor 'iermittingthe introduction 01 an irrigating fluid and simultaneous discharge ofexcretions from the duct into which the anuscope is inserted.

The main object is to provide a device of this character which is moresanitary, more convenient of manipulation and less irritating to thepatient than has heretofore been practised.

One of the specific objects is to make the joint between the taperedentrant member and main body of the tube substantiallysinooth so thatthe surfaces o'l both members will be con- 'tinuous or free fromirritating obstructions.

A further object is to provide the medial portion of the tube with anannular head of suca construction that it will readily enter the ductand allow the latter to contract thereover at the rear side thereoi toassist in retaining the tube in operative position when making theexamination or diagonsis of the condition of the duct. 7

Another object is to provide the tube with a protective shield or stopflange to prevent its excessive entrance into the duct.

it lurthe object is to enable the device to be readily connected to ordetached from a suitable battery-containing handle whereby the anuseopemay be more conveniently proj ected into and withdrawn from theanatomical duct and at the same time to supply the necessary current forlighting the lamp.

Uther objects and uses rela ing to specific parts of the device will bebrought out in the following description.

As illustrated, the anuscope comprises a tubular member -1- having anopening 2 extending therethrough troni end to end, the distal end ofsaid tube being curved laterally to one side of the opening and providedwith a tapered entrant extci'lsion --3 swivoled thereto to turn about anaxis atan agle to the axis of the tube --1 and this swivel connectionbetween the part 1 and 3-- may be made in any suitable manner but, asillustrated, the distal end of the memher i is provided with a reduced.cylindrical stud or pivotal pin t projecting forwardly therefrom andupon which is journaled sleeve 5- held in place against out ward axialdisplacement by a head 6-- on the outer end of the pivotal pin .l-.

'IlThe rear end oil? the extension is provided with a socket 7- forreceiving the sleeve which is tightly held in the socket by pressing theextension 3 endwise over and upon the sleeve after the latter has beenproperly mounted upon thepivotal pin 4:.

The sleeve -5 is held against axial movement between the head 6 and theshoulder as 8 formed by the reduction of the diameter of the pivotal pin4 while the socket 7is slightly longer than the pivotal pin 4 and itshead -6- to enable the rear end of the tapered extension --3- to bepressed firmly against the shoulder 8 when forcing it over and upon theperiphery of the: sleeve thus forming a tight connect-ion between thesleeve and extension 3- and permitting said extension with the sleevetherein to be rotated about the axis of the pivotal pin which fitssnugly within the sleeve to prevent radial movement of the parts 1 and2' relatively to the pivotal pin.

This pivotal connection between the tube 1 and tapered extension 3 iswholly at one side of the distal end of the opening -2 through the tubewhile the adjacent ends or meetingfaces of the sections 1 and 2 are ofthe same diameter and approximately the same degree of taper so as toestablish a substantially smooth joint and continuous curved surfaceacross the joint to avoid irritation of the duct into which the devicemay be inserted.

The obj set in curving the distal end of the anuscope laterally is tofacilitate its entrance into the duct while the swiveled'taperedextension 3 directs such entrance through more or lesstortuous-parts ofthe duct by antomati'cally conforming to the direction of adjacentportion of the tube and thereby to retain the anuscope in operativeposition dur ing examination of the interior of the duct. "The rear endof the tubular section -1 terminates in a plane diagonal to the axisthereof and approximately tangential to the curvature of the adjacentside of the distal end of said section so that the opening in the distalend of the tube is somewhat larger than the interior diameterof the tubethus permitting the examination of a relatively wide area of theinterior of the duct into which the device is inserted by visualobservation through the proximal end of the tube.

Theinner wall ofthe distal end of the opening 2-' to which theextension3- is attached is inclined at 10- forwardly and inwardly toward the axisof the tube to afford a more solid support for the extension 3- withoutmaterially contracting the opening in the inner end of the tube.

- The inclination of the wall -10 relatively to the axis of the tubeapproximates the angle of inclination of the end face as 1'l. of thetube so that the apex of the angle between the two surfaces will beapproximately in the axis of the tube 1 and just at the rear of thejoint as 12- between the set:- tions -1 and 3, the object of whi -h isto facilitate the entrance of th anuscope into the duct and the drainageof excretions therefrom through the tube.

Aside from the inclined distal end --1l-- of the tube the crosssectional area of the exterior thereof and of the e dension 3- iscircular and smooth to enable those parts to readily enter theanatomical part under examination and also to be turned about its axiswithout excessive irritation of that part, it being understood thatduring the turning movement of the tubular section -l in the duct theextension 3 will remain in its adjusted position or may assume any otherposition of least resistance.

The tubular section -lis also pl'tlYltltltl with a rearwardly flaringannular flange 13 of greater diameter than and in axially spacedrelation to the bead to mm .4

stitute a stop shield for preventing excessive entrance of the anuscopeinto the terminal end of the alimentary canal.

The proximal end of the tube 1- is eylindrical, both externally andinternally for receiving a lamp case 1-l;- and an irrigator 15-respectively The lamp case is placed telescopically over and upon theproximal end of the tube with a reasonably close sliding andcircumferential lit to permit relative angular movement of those partsas may be required for convenience of manipulation of the auuscope.

An electric terminal post -l(' is secured in an o1:)ening in one side ofthe lamp case -1 l to extend radially through and beyond said side forreceiving and suppm'ting at its inner end a lamp socket lT eontainiiugan electric inmindescent lamp -18 the outer end of said post beingprovided with a coupling member -l9- for uttzu-lnnent lo a suitablebattery handle -2() and is also provided with a radial lug 2l for comncction with cord coupling 22, i i desired, without removing thecoupling member 19.

The terminal post .l(i and its cord 'ollpling 22 are similar to that setforth in my application Serial, No. 11.405, tiled Feb. 25, 1925, allowedSeptember 14-. 11927, and application Serial No. 226,726 liled October.17, 1927.

The battery coupling section -19- is similar to that set forth in mypending application Serial No. 220,460, filed Sept. 19, 1927,

ill)

llll) llll "which also shows a battery handle similar to the batteryhandle of this application and adapted to contain one or more batterycells and a suitable switch for controlling the current to the lamp.

The lamp case -1lis similar to that shown in my pending applicationSerial No. 226,726, previously referred to and not necessary to hereinfurther illustrate or describe,

except that its proximal end is provided with a lens supporting frame 2Scarrying a lens -24, both of which are movable to and from a positionacross the opening in the tubular lamp sass.

In the present application the lamp socket -17- is secured directly tothe inner end oi the post -16 so as to project into the proximal end ofthe tube -1 but in spaced relation to the walls thereof and preferablynear its axis so as to project the rays of light tliorwardly through thetube and into the duct into which the anuscope is inserted, said lampbeing also located some distance to the rear of the distal end of thetube which protects the same against contact with the walls of theanatomical duct.

The irrigating device -15-- comprises t metallic tube 25- having anexterior diameter substantially equal to the interior diameter of thetube 1- to fit telescopically therein With a close friction fit topermit rela tive angular movement of both tubes, the tube -Q5 beingprovided with an enlarged outer end head -26- adapted to abut againstthe outer end of the tube 1- to limit the inward movement of the tube25-- as shown in Figure 7.

lhe outer end of the head -26- is provided with a reduced tubular nipple27-- at an angle to the axis thereof? and mainly at one side of saidaxis to deflect any on cretions from the anatomical duct entering thetubes -1 and -25 from the outer end of said tubes.

A relatively small metallic tube 28- is secured in an opening in theouter diagonal wall oi. the head -23 to extend into and through the tube-25- parallel with, but wholly at one side of the axis of the tubes--land -25" and has its outer end adapted to be connected to anyavailable source of supply for a suitable irrigating fluid which may beprojected through the tube -28- and into the anatomical duct underexaniiination or treatment.

The inner surface of the tubular member -1-- may be coated with a blacklining adhesively secured thereto to permit a more direct projection ofthe light rays from the lamp to the a il'ected part under examination ortreatment.

What I claim is z 1. An anuscope comprising a tubular member open atboth ends, and a tapered extension swiveled to the distal end of thetubular member to rotate about an axis at any oblique angle to the axisof said member.

2. An anuscope comprising a tubular member having its distal end curvedlaterally, and

a laterally curved extension sWiveled to the distal end of the tubularmember to rotate about an axis at an oblique angle to the axis of saidmember.

3. An anuscope comprising a tubular member having its distal end curvedlaterally and a forwardly tapered extension swiveled to the distal endof said member to rotate about an axis at an oblique angle to the axisof said member.

l. An anuscope comprising a tubular member open at both ends and havingits distal end face disposed diagonally to its axis for enlarging theadjacent end opening, the inner wall of the opening opposite thediagonal end time being inclined forwardly and inwardly toward said axisto serve as a deflector for liquid injections through the tubularmember.

5. .An anuscope comprising co-axial tubular members telescopicallyassembled for rel ative turning movement, and a tapered extensionswiveled to the distal end of the entrant member Wholly to one side ofthe axis of the tubular member for relative turning movement.

6. An anuscope compr'sing co-axial tubular members telescopicallyassembled for relative turning movement, and a forwardly curvedextension swiveled to the distal end. of the entrant member wholly toone side of the axis of said members for relative turning movement.

7. An anuscope comprising co-axial tubular members telescopicallyassembled for relative turning movement, the entrant member having itsdistal end curved laterally, and a laterally curved tapered extensionswiveled to said curved end for relative turning movement.

8. In an instrument of the character described, tubular member having aperiph eral flange near its proximal end and its distal end providedwith a laterally curved tapered extension, said tubular member having aperiphcral head between said flange and laterally curved taperedextension to assist in retaining the tubular member in the organ undertreatment.

In witness whereof I have hereunto set my hand this 17th day of New,1927.
